NEW FINDING OF NON-INDIGENOUS JAPANESE CYPRINID FISH IN THE CZECH REPUBLIC

Ginbuna Carassius langsdorfii endemic species of Japanese archipelago have been found in European waters. The origin of European records and the environmental impact remain unclear. The present paper reports on the population of this species discovered in a small natural pool in South Bohemia. Genetic markers were employed since morphological characters failed in species identification. Although the population was clustered in the mitochondrial lineage of C. langsdorfii, genetic distance and morphological difference were found largely significant when comparing to other ginbuna individuals found in Europe. The phylogenetic position is further discussed.
